KPF Series High-Flow Regulator

Brand: Swagelok Company
The KPF series provides minimum droop across the flow range with high accuracy of outlet pressure.
Features
  • High flow coefficient
  • Balanced poppet for minimal supply-pressure effect
  • High-flow, dual-gauze type filter positively retained in inlet port
  • Maximum Inlet Pressure: psig: 6,000 (bar: 413.7, kPa: 41,370)
  • Pressure Control Range: psig: 0 to 1,000 (bar: 0 to 68.9, kPa: 0 to 6,895) through psig: 0 to 4,000 (bar: 0 to 275.8, kPa: 0 to 27,580)
  • Maximum Operating Temperature:
    • 80°C (176°F) with PCTFE
    • 200°C (392°F) with PEEK 
  • Process Connection: 1/2" Female NPT (Inlet and Outlet), 1/4" Female NPT (Gauge Ports)
  • Actuator: Knob, Antitamper nut
  • Materials of Construction:
    • Enclosure: 316 Stainless Steel
    • Piston: 316 Stainless Steel
    • Poppet: S17400 Stainless Steel
    • Seat: PEEK, PTFE
    • Seal: Fluorocarbon
